I found a great deal on a large size Rush. I'm not worried about cockpit length, but I'm not sure that the front end would be tall enough for me due to the short HT height (it may be fine, dunno). I don't want the seat to tower above the bars. I suppose I could install a taller stem if needed, but I wonder if that would jack-up the handling. Any thoughts from taller riders, especially those riding a Rush?
